In this thesis, an average current-mode controller is analyzed for controlling power electronic converters. This controller consists of two loops. An inner loop, which senses and controls the inductor current and an outer loop, which is used to control the output voltage and provide reference voltage for the inner current loop. An average current-mode controller averages out high frequency harmonics it senses from the inductor current to provide a smooth DC component. This can be used as a control voltage for a pulse width modulator and produce switching pulses for the power electronic converters. An average current-mode controller can also …

Measuring The Acute Physiological Effects Of Leptin In The Carotid Body, Richard Laurence Pye
Browse all Theses and Dissertations
Obesity is the healthcare crisis of our generation. Circulating levels of the adipokine leptin are proportional to adiposity and in addition to its role as a satiety factor leptin has been shown to have a host of pleiotropic effects. Among these effects is its role as a respiratory stimulant where it has been shown to have both whole body and central stimulatory effects on breathing. Porzionato et al. (2011) showed that leptin and leptin receptors are selectively expressed in the chemosensing type I cells of the carotid body. Carotid bodies are small chemosensitive organs that act as the primary peripheral …

Organophosphates (OPs) are highly toxic insecticides and nerve agents that have been designed to inhibit the hydrolysis of acetylcholine by binding to the serine active site of acetylcholinesterase (AChE). They are one of the most common causes of human poisoning worldwide and are frequently intentionally used in suicides in agricultural areas. For this reason, there is a need for therapeutics to rescue those from intoxication. Obvious ethical concerns prevent humans from being subjected to OP exposure for therapeutic efficacy and safety testing. Therefore, animal surrogates for humans must be appropriately selected. A new paradigm, described herein, incorporating both in silico …

Modification And Evaluation Of A Brain Computer Interface System To Detect Motor Intention, Christopher V. Hagerty-Hoff
Theses and Dissertations
It is widely understood that neurons within the brain produce electrical activity, and electroencephalography—a technique used to measure biopotentials with electrodes placed upon the scalp—has been used to observe it. Today, scientists and engineers work to interface these electrical neural signals with computers and machines through the field of Brain-Computer Interfacing (BCI). BCI systems have the potential to greatly improve the quality of life of physically handicapped individuals by replacing or assisting missing or debilitated motor functions. This research thus aims to further improve the efficacy of the BCI based assistive technologies used to aid physically disabled individuals. This study …

Strategies for improving student success are particularly important in high-demand fields like science, technology, engineering, and math (STEM). As the U.S. experiences a decline in skilled STEM workers and a growing number of racial/ethnic minorities, it is critical that more attention be paid to the college success of underrepresented populations majoring in STEM. While some strategies for increasing STEM student success have focused on social-psychological factors such as academic self-efficacy and resilience, little attention has been given to these factors among specific minority groups in STEM such as Black men. To extend the current literature, interviews with 27 Black male …
